0.2 pH units isn't much -- a pool will vary that much from day to day, just because 'it want's to'!

TA is bit low; you can add a box of borax and raise both pH and TA a bit. Or, you can add a box of baking soda (5 - 10 lbs) which will mostly raise TA.

I've tried to avoid getting rigid with the numbers -- there are many, many combinations of values that will work. Being very specific about what your numbers MUST be is easier to understand, but harder to carry out.

We've opted to make your brain work more, so you can work less on your pool!
